In recent years the inputs of Asian atmospheric pollutants (for instance, acid pollutants, Asian dust, biomass burning and mercury) to Taiwan via long-range transport have been widely paid attention. In order to clarify the intercontinental and regional transport and collect the atmospheric baseline data, the Lulin atmospheric background station (LABS, 2862 m) at Mt. Lulin in central Taiwan has been operated on 13 April 2006. This project integrates those researchers in the fields of precipitation chemistry, gas chemistry, aerosol chemistry, atmospheric mercury and radiation to test the instruments, conduct data analysis and construct long-term database. Till present time, we find that the average concentrations of CO, O3 and PM10 are about 72 ppb, 23.7 ppb and 8.7 g m-3, respectively. Monthly tendency of above pollutants indicates that the concentrations decreased from April to July with a lowest average, and gradually increased to the highest values in October. We make a lot of efforts on extending the collaborations with USEPA, NASA, NOAA. We also have participated international experiments such as ABC and BASE-Asia. We have constructed the web site of LABS (http://labs.org.tw).
